A2K2, WinXPPro. Mail Merge to Access Jet4 db. Created odc pointing to XYZ.mde. Works fine. Edited odc file to point to XYZ.mdb. Doesn't seem to recognize new data source. Same table, same mdw. checked if any other odc files on my computer. None. Even after editing odc it still points to data in the XYZ.mde db. Is there some internal file number in the odc that I also need to edit? Anything else I should check?
